arm64: dts: allwinner: h616: Change RG35XX Series from r_rsb to r_i2c

Change the Anbernic RG35XX series to use the r_i2c bus for the PMIC
instead of the r_rsb bus. This is to keep the device tree consistent
as there are at least 3 devices (the RG35XX-SP, RG28XX, and RG40XX-H)
that have an external RTC on the r_i2c bus.
